need guide on codec-engine OMAP3530 on beagleboard

Hi,

I am working on developing speech processing application on OMAP3530. I used beagleboard running Angstrom linux and I work on PC running Ubuntu. So far I have been able to build dsplink and it samples and xdais samples. Right now I'm trying to build codec-engine examples. but it failed. I use CodeSourcery 2009 arm GNU/Linux toolchain.

1. Default user.bld use target:"gnu.targets.arm.GCArmv5T" but it failed to found it in packages path so I changed to target:  "gnu.targets.codesourcery.GCArmv5T" which exist but when build it gives following error:

config.bld: Running the version from Codec Engine Examples.
config.bld: loading user build configuration file /home/beagle/development/ce-examples/user.bld
js: "/home/beagle/development/ce-examples/user.bld", line 152: gnu.targets.codesourcery.GCArmv5T: 'LONGNAME' is sealed

gmake[1]: Leaving directory `/home/beagle/development/ce-examples/ti/sdo/ce/examples/codecs/viddec1_copy'
gmake: *** [all] Error 2

How to fix this?

2. If I changed Linux distribution in beagleboard to Ubuntu do I need to rebuild all codec_engine, dsplink and others?

3. I do not install DVSDK since Community Linux based SDK is not avalailable? do I need this for my work? Can I user other DVSDK?

4. For my work (speech processing), this is rough idea that I have : record sound using ALSA (GPP), using DSP as speech processing (codec and others) and then using ALSA (GPP) to playback. Is this right? is there any example that can provide good starting point for this?

Thank you.
